JOSEPH A. GROEBLI, OF NEW YORK, N. Y., ASSIGNOR TO THE KURSHEEDT MANUFACTURING COMPANY, OF SAME-PLACE.

FESTOON APPARATUS.

SPECIFICATION forming part of Letters Patent No. 609,429, dated August 23, 1898.

Application filed December 31, 1897. $erial No. 664,813. (No model.)

To all whom it may concern:

Be it known that I, JOSEPH A. GROEBLI, a resident of the city, county, and State of New York, have invented certain new and useful Improvementsin Festoon Apparatus, of which the following is a specification.

My invention relates to what is technically known among embroiderers as festoon apparatus, which may be defined as an apparatus for producing an embroidering-stitch closely resembling the ordinary buttonholeedge stitch made by hand, and is directed principally to devices for spreading the loop of 'the needle-thread and to hold the same open, so that the needle may pass through the said loop upon its next passage, all of which will be fully hereinafter set forth.

The invention will be understood by referring to the accompanying drawings, in which- Figure 1 is a sectional side elevation of enough of the elements of an embroideringmachine to illustrate my said invention. Fig. 2 is an enlarged View of the festoonstitch. Fig. 3 is a front or face view of a form of festoon-hook embodying my invention. Fig. 4. is a rear view thereof; and Fig. 5 is a side elevation thereof, looking from the left in Fig. 3 and from the right in Fig. 4.

The device shown in Figs. 3, 4, and 5 is for the purpose of spreading the needle-loop and holding it open, as will be explained.

Referring particularly to Fig. 1, a is the needle-bar or other needle-carrier carrying the needle I), and d a rail or other carrier carrying the festoon hook or. hooks e. The fabric to be operated upon is represented by the dotted line f. The festoon-hook is shown in the present instance as a shank e, provided with a downwardly-depending extension e from which projects an upwardly-extending extension e The said extensions 6 and e form a loop-supporting means, here shown as a bend or elbow e, in which the needle-thread rests when the apparatus is at work. The extension e is provided with an inclined edge or guide 6, and the extension e is provided with the inclined edge or guide e, which edges or guides are shown as placed at angles to each other. As will be well understood, the needle makes the usual to-and-fro motion into and out of the fabric, and the festoon-bar is given a rising-and-falling motion, making one complete oscillation to every two strokes of the needle-bar. Letus'follow these motions. The needle recedes from the fabric, carrying with it the needle-thread, which is thereupon, as the festoon apparatus rises, caught by the intersecting guides of the festoon-hook and guided thereby until the loop or bight of the thread falls into the broad portion of the hook e which broad portion constitutes the loop-supporting means. The needle thereupon reenters the fabric, so that the loop is now in the form of a triangle, as will clearly appear from an inspection of Figs. 3 and 4, wherein 1 represents the point Where the needle left the fabric as the festoon-hook came into operation, and 2 represents the point where the needle has now entered the fabric, the thread 3 being, as shown, in the form of a triangle. The needle passes out of the fabric and again enters the fabric within the triangle so formed-for instance,'at the point marked 4. The festoon-hook descending releases the loop,and again ascending engages the needle-thread,as before,whereupon the described cycle of operations is repeated. The character of the stitch will clearly appear from an inspection of Fig. 2, wherein the thread 3 is represented as in the form of a buttonhole-edge stitchj The loop-supporting means should be sufficiently wide to hold the loop open far enough to enable the needle to be reentered into the loop upon its second return stroke, as described, the guides e and e guiding the thread to the appropriate position-to wit, that shown in Figs. 3 and 4- it being understood that the thread lies in the loop-supporting means.

What I claim, and desire tosecure by Let ters Patent, is-

1. A festoon-hook, substantially as herein described, the same consisting'of a loop-receiving bight or bend having the gniidese e 5 leading thereto, the said guides being inclined with respect to each other and inter secting each other.

2. A festoon apparatus comprising loopsupporting means and intersecting guides for guiding the loop to the loop-supporting means whereby the loop will be conducted to the leop-supporting means and thereby held open suflieiently far to receive the needle upon its returnstroke whereby a festoon-stitch may be formed.

3. A fest00n-h00k bent up of sheet metal and having the bight or bend e therein and the edges or guides e 6 leading thereto, the said edges or guides intersecting each other,

whereby the said edges 01' guides Will guide a thread into the said bight where the same will be held open to receive a needle.
